the groove 42 the said inner wall by means of the screws 27, and between the meeting faces, a paper, or other suitable gasket 27 is employed. On the upper face of this inner wall there is formed a'vert'ica'l head 28, while a similar bead 29 is formed on the'upp'er face of the The beads 28 and29arevto prevent oil from flowing on the upper, surfaces of the ad acent parts on which they are formed,

end of the Disposed on the upper end of the bolt, and arranged within the upper end of the sleeve 34, is abeveled disk 38, a'nut39 beingengaged on the bolt to properly clamp; the parts together, but permitting free rotation of the sleeve on said stud. -Extending" laterally from the sleeve 34 is a clamp 40, inwhich is secured one end of one of the pumping rods 7 Formed in the face of the inneriwall of the channel of the rim 17 is a oircumscribing oil groove 42,and in the adjacentface of the stem or web of the retaining ring 26there isformed a similar groove 42, suchgrooves being at thesame level, and cooperating to form a circumscribing channel, Inthe inner face of'the power 'ringl E), at-thesame level as the grooves 42 and 42 is a groove 43, said groove having communication lwith by neans'of a series of transverse oil passages 44, formed through the vertical web 26 ofthe retaining ring 26. Extending from the groove 42is an oil passage 45, which registers with the lower end of the vertical oil, passage 46, formed in the inner portion of the head of the'retaining ring '26. Properly securedin the upper end of the'passage 46 is one end of the oil pipe or conduit 47. Secured on the upperend of the shaft12 is" a sleeve 48, and formed on the upper end of said sleeve is'a cup 49. Connected to the bottom of said cup 49 is the other endof the before-mentioned pipe 47. It willbe noted that the pipe 47 leads to a point of the eccentric 14'near the shaft Q12, through the retaining ring 26'. a f

iAt theupper' end of the shaft'12, and prop- "erly fitted withinithe bearings 50, is a can member 51, for supporting said shaft. This cap is formed with an upwardly extending peripheral fiange 52', throughfwhich are disbeads the posed, and secured, the'inner ends of the radially extending brace rods, which are adapted to be anchored at a suitable point.

Secured in the bottom wall of the member 51, isa suitable lubricant container 57 preferably of the automatic gravity feed type. Passing through the step 22, of member 14, at a point opposite the passage 45, is a vertica-loil passage 58, and secured in the lower end of said passage is an oil pipe 59.

The member 15 is of similar construction to that described in connection with the member- 14, and has the power ring 60 disposed in the channel, such ring being held in the channel by means of the retaining ring 61, and being provided with upwardly extending studs 31, constructed in a manner similar to the studs 31, of the power ring 19.. The power ring 60, and the inner wall of the channel, are oil grooves63 an'd 64, between which com munication'ls established by means of the oil passages 60, formed through the vertical web of the retaining ring 61.v The groove 64 has the vertical oil passage 65 which registers with the passages 66, in the head of the 'retaining ring 61. The lower end of the beforementioned oil pipe 59 is secured within the upper end of this oil passage 66. The lower face of the powerring 60 is formed with the annular oil groove 67, similar to the groove 24, of the ring .19. Leading downwardly through the bottom of the channel of the member 15, from the ledge 68, is an oil passage 69, within which is secured one end of i the oil pipe 70, said pipe having its other end secured in the outer end of the oil passage 71, formed in the hub member 16, of the member 15, and which passage extends to a point di- 7 rectly above a bearing 72, located in the upper portion of the housing 10, and which surrounds the shaft 12.

' The operation of the device may be briefly described as follows: Power being applied to the worm shaft 11, to rotate the same,,the vertical shaft 12 will also be rotated, carrying around the, channeled members 14 and 15. As the members 14 and 15 rotate about their axes, the power rings will be given eccentric rotary movements, whereby to cause the reciprocation of the pumping rods 41, and the operation of the pumps at the wells.

By removing the nut 39, from the bolt,

the disk 38 maybe lifted from said bolt,

whereupon the operator may slip the sleeve 34 fromthe stud 31, or slip a sleeve thereon.

Thus the number of pumping rods may be increased or diminished, in accordance with the number of wells to'be operated. What is claimed is:

1. A pumping power unit including a shaft, an eccentric channeled member mounted' on the shaft, a power. ring seated within the channel of the me1nber,and a'retaining ring disposed between the power ring and formed, respectively, with the 5 shaft, aneccentric member mounted on the i is shaft and having a circular channel, a power ring seated withinthe channel and-spaced from one wall of said channel, and a retaining ring T.-shaped in cross section having its web disposed in the said space and its head overlying the eccentric member and the r,

powerringyandmeans removablysecuring a portion of the head of the retaining, ring .to theeccentricmember.

" 3. A power ring for a pumping power unit A including a body, upwardly extending studs on the body, pumpingrodsjeach having a terminalImeansmovably engaged on a stud, andmeans for retaining said terminal means on the stud, said retaining means including means engaged with said terminal means,-

and means on the stud engaged with the terminal engaging means, for holding the lat- I terin position. r

l .4. A power ring for a pumping power unit including a body, a plurality of upwardly extending studs on the body,'each of said studsvhaving a vertical opening inits upper end opening through a sideof the stud, a

an pumping rod having a terminal sleeve engaged on the stud, a boltheld in said opening, and a disk held on said bolt in retaining rela-v tiontosaidsleeve.

f'. 5. A power ring for a pumping power unit, i

v including a body, a plurality of upwardly extending studs on the body, each of'said studs having an opening in its upper endextending through the upper end'of the stud and the'side thereof adjacent said vend,-a" 40 pumping rod havingaterminal movably-engaged on-said stud, a fastening meanshe'ld within the stud opening by the said'terminal, V and means held" engaged with said rod terminal by said fastening means.
